A KINETIC STUDY ON THE CARBOTHERMIC REDUCTION OF ZINC OXIDE FROM ELECTRIC ARC FURNACE DUST
In the present study, reduction of zinc oxide from the pellets made of steelmaking electric arc furnace dust has been investigated. Effects of such parameters as the type of carbon material (graphite, coke and charcoal) as well as time and temperature on the reduction reaction have been examined. The reduced (dimensionless) time method was applied to perform a kinetic analysis of the system. Ex...

متن کاملReduction of Costs of Iron Production by Changing Parameters of the Mixed Blast-furnace Wind
The blast-furnace process consists of a large number of processes that are physicochemical, thermal and mechanical interconnected processes. In addition to main processes consisting of iron oxides reduction, pig iron and slag melt creation, also realised are fuel combustion, gas flow, charge and melt flow, dissociation and other reactions in the solid and liquid phases. Inputs to the blast-furn...
متن کاملRECOVERY OF IRON FROM LOW-GRADE HEMATITE ORE USING COAL-BASED DIRECT REDUCTION FOLLOWED BY MAGNETIC SEPARATION
In the present work, iron recovery from a low-grade hematite ore (containing less than 40% iron), which is not applicable in common methods of ironmaking, was studied. Non-coking coal was used as reducing agent. Reduction experiments were performed under various coal to hematite ratios and temperatures. Reduction degree was calculated using the gravimetric method. Reduced samples were subjected...
